I use a Lenni. Sometimes my quilt on the take-up roller will be tight on the side with the brake and somewhat looser on the other side so that my pantograph pattern will be off on that side 1/4 to 1/2 inch. Do I need another brake on the opposite side or just continue to tighten the one brake. Or, am I missing something I should be doing?

I am a beginner with a Lenni Longarm. I adjust the tension so that the stitches look great. Fifteen minutes later, the back stitches are tight or the thread is breaking. If I get the tension to hold, quilt several lines with the pantograph and stop for the evening, the next time I turn the machine on, the stitches are off. I do nothing but turn the machine off and on. Help!
